I noticed that every item needs to have a designated location amongst the lists you've already created, but not everything needs to be categorized...
Describe the solution you'd like
My solution is an Unlisted location when you create a task.
It can also be shown in that set of locations you see in the main screen on the left, preferably in a different style to distinguish it, giving it a different icon seems to do the sufficient job without being too much.
Describe alternatives you've considered
An alternative is to not have it shown in that set of locations, but I think it's convenient if you want to view every unlisted task
